    cobra 25 ltd classic st/mosfet

    I just took a look at this "mod." hmmm, wonder how many actually got it to work. ? with the driver TR8 changed to a 2166 - maybe not enough RF drive to TR8, so tune up L14. and L13 for maximum to drive TR7. and L10 for output level. so watch the RF output on the meter, and tune up, starting...

    Cobra 2000 GTL

    never mind. I assumed this 142GTL main board is the same as a 2000. I opened it up. this 142 is from an old guy and said it was in his closet for many years. it looks like it was never opened up before. it still has/had the paper gasket at the front of the cover, and it is all decomposed...

    Cobra 2000 GTL

    I listened to your audio problem a few times. the radios I had had more random loud crackling noise, sounding like listening to 75 meter SSB on a summer night with thunderstorms around. it was obvious the TA7222 was bad, also knowing that the radios came from noisy trucks where the volume was...

    Cobra 2000 GTL

    hmmm. yes, I had some radios with that problem. the audio amp IC TA7222 goes bad. all that crackly noise out the speaker. more tests: put in PA mode and connect a speaker to the "PA SP" jack. listen for the noise. - Transmit in AM mode and listen on another radio. key up, MIC gain...

    "they move the rig near Belmont , LA. We've been working in Coushatta LA. Got to experience my first earthquake there. Strange sensation when the ground starts shaking you and everything around you" OK, you are working up north west from here. In "Redneck Louisiana" as it is known. I am way...

    Would like to see some pictures of your pet's.

    yeah, I get cats n dogs showing up at my house sometimes. somebody told me that "pets find you, you don't find them" So I have taken a few animals in over the years. Or I find a home for them, since I live on a roadway with traffic, and in the back yard is a bayou with alligators and water...

    How to Repair With What You Have on Hand or GT5000 Fix the Fix.

    . Yes, back then. as young kids in that area. We used to ride our bikes to that Grauman's Chinese Theatre and watch people get their plastic molded souvenir from that machine outside. Ride over to The La Brea Tarpits, and we went to an inside display, and were throwing rocks and sticks into the...

    How to Repair With What You Have on Hand or GT5000 Fix the Fix.

    oooh yeah! I remember all that. two of us on one bike sometimes. the banana seats had sparkle reflectors in the design. and those type of handlebars were funny at the time. and a five-speed stick shift on a bicycle, how revolutionary! And go ride around on a warm Los Angeles Saturday...

    How to Repair With What You Have on Hand or GT5000 Fix the Fix.

    . yeah! I remember growing up in Los Angeles late 60's to early 70's. Tonka trucks built tuff. They had that "steel" symbol on them. We trashed on them in a dirt spot in the back yard. hard to break them. Also remember them Schwinn bicycles, the Stingray, with a "sissy bar" and that big flat...

    How to Repair With What You Have on Hand or GT5000 Fix the Fix.

    The steering on my 20-year-old Troy-Bilt Pony (MTD/Craftsman/Yard Machine) is going out also. It is similar, if not the same as posted here. Now I gotta take a look at it.

    This thing is awesome!

    yes, I remember them devices! Advertised on the Art Bell show, (C.C. Crane) and maybe shows on WWCR shortwave. Back when they had William Cooper on, and others. maybe 7435 kHz??? So I made a few of them. Just make a big multi-turn loop antenna with a variable capacitor to tune in. And...

    Shortwave radio repair.

    I work on and repair that kind old tube stuff. but it would cost a lot of money to send it out. do you live around Baton Rouge. ?? and maybe a hard to find transformer or tube is needed. or many capacitors need replacing. what is the apparent problem with that receiver? I just gave a guy all...

    mod for receive audio to come out of PA speaker. (RCI/Galaxy)

    OK, worked on a Connex 3300HP that had no PA or Echo. the problem was in the echo board, and I replaced it. Now PA works. and echo works, but he does not use that. But........ this guy claims that while he is outside of his truck, in PA mode, he can get radio calls also in the PA speaker on...

    Tested a portable elevated "V" today

    a few years ago, on 17 meters, there was a guy that vacationed down in Jamaica and he had an antenna set up like that, right on the beach several feet off the sand. I would talk to him during his Winter vacation down there. And also there was a guy that would go to a park near Phoenix AZ and...
